Face Matching Demo

Here is at the moment what we can do with the face matching neural network.
You can find all material for this demo on the download page.

Quick start instructions :

1) Launch the executable program file.
2) Load a trained neural network (NNetwork.nnpc).
3) Load an image to scan (some are given in the images sub directory).
4) Finally click on "Search Face" button.

Advanced settings :

If you try with the given image everything should be fine but with your own images detection may not be as good. The reason is that the neural network is set to detect face that are quite big on the picture. To customize those settings just click on the "Edit Neural Network" button :

The pattern recognization editor is divided in three panels, on the right side you can recognize the neural network editor from the neural network library and on the left the training of the neural network and the searching parameters. Let's take a look at the searching parameters :

Windows interval : it's the interval in pixel between each window submited to the neural network, to improve quality of detection you should decrease this value but at the same time it will increase searching time.
Threashold : for each window the output value of the neural network is compared to this threshold, if no face are detected you should decrease this value.
The scale parameters alow you to set the minimum and maximum scale to search for face. The detection is better if there is an important number of scales.

You can find detail on the learning panel on the training page.
